COMBINED HARROW AND ROLLER.

SPECIFICATION forming part of Letters Patent No. 669,679, dated March 12, 1901.

' Application flied May o, 1900. sean No. 15,615. No model.)

To all whom t may concern:

Be it known that I, LORENZO Dow BUTLER, a citizen of the United States, residing at Orandon, in the county of 'Forest and State of Wisconsin, have invented a new and useful Combined Harrow and Roller, of which the following is a specification.

My invention is animproved combined harrow and roller, one object of my invention being to provide a combined barrow and roller which is adapted to perform the operations of harrowing and rolling the ground either simultaneously or separately.

A further object of my invention is to provide means whereby the combined harrow and roller may be readily turned in a field.

A further object of my invention is to simplify the construction of the frame.

My invention consists in the peculiar construction and arrangement of parts hereinafter more fully set forth, and pointed out in the claims. Y

In the accompanying drawings, Figure 1 is a perspective view of a combined harrow and rollerembodying n'iyimprovements. Fig. 2 is a vertical longitudinal sectional view of the same. l

The frame 1 of the combined barrow and roller comprises the pair of side bars 2, the cross-bars 3 at the ends thereof, and the seatbars f1, the latter having their ends downturned and bolted to the cross-bars 3, as at 5. The ends of the cross-bars are bent at right angles tovform the portions 6, which bear against the outer sides of the side bars 2 and are bolted thereto, as at 7. Bearing-blocks 8 are bolted to the cross-bars 3 at the ends thereof, said bearing-blocks forming bearings for the vertical Shanks 9 of caster-frames 10, in which are journaled caster wheels 11. Hence the frame 1 is provided with supporting caster-wheels located at its corners and is adapted to be readily turned. A drafttongue 12 is connected to the cross-bar 3 at the front end of the frame, as at 13. A seat 14 is mounted on the seat-bars 4 and is adapted to slide longitudinally thereon.

U -shaped barrow-frames (two or more) are pivotally mounted between the side bars 2, as

.at 15, and said harrow-frames are disposed in front and rear of the roller 16, which is transversely disposedwithin the frame 1 and has its shaft 17 journaled in bearings formed in the side bars 2. As here shown the roller is formed in two sections a., which are independent of eachother; but the roller may be composed of any suitable number of sections as may be required. Each harrow frame is provided with a lever 18, whereby it may be turned on its pivots and caused to move upward or downward with relation to the frame 1, and barrow-teeth 19 have their upper ends attached to the transversely-disposed portions of said U shaped harrowframes. The length of the said harrow-teeth is such that by moving the levers 1S rearward, the barrow-frames being thereby depressed or lowered, said barrow-teeth are caused to engage and operate in the soil in front and rear of the roller, hence adapting the combined roller and harrow to perform the operations both of rolling and harrowing the ground at the same time. When by means of the levers 18 the barrow-frames are moved upwardly, so as to disengage the barrow-teeth from the soil, the machine is adapted to be used solely for the purposes of rolling the ground. In order to secure the harrowframes at any desired adjustment, I provide sector-frames 20, which are secured to one side of the frame 1 and have engaging teeth 21 on their inner edges which are adapted to engage the levers 18 and lock the same, and hence the harrow frames and teeth, when adjusted.

When the barrow-frames are turned downward .to the full limit of their movement, the barrow-teeth sustain the weight of the machine,and the frame, together with the roller, is raised, whereby the weight of the roller is imposed upon the harrows and the latter caused to operate deeplyin the soil. The harrows may be adjusted so as to cause the roller to bear upon the soil to any desired extent as may be necessary to produce the best results when using both the harrows and the rollers to stir and pulverize the soil.. The roller being disposed in the center of the frame and the seat being adapted to be moved forward or rearward, the weight of the driver may be imposed upon either the front or the rear harrow, as may be desired. Another function of the caster-wheels is to support the corners of the frame 1 and distribute the IOO Weight of theoombined harrowwand roller throughout the length and breadth of its frame, and thereby cause the harrows to operate smoothlyT and evenly in the ground.

Having thus described my invention, l claim- 1. In a combined roller and harrow,the com-v bination of the main frame, the centrally-dise posed roller having its bearings therein,the vertically-movablesupporting caster-Wheels, the harrow frames, said oaster- Wheels and barrow-f rames being in front and rear of said roller, levers to raise and lower the harrowframes, independently of eachother, the seat, and means to shift the same forward and rear- Ward of the roller, substantially asdescribed.

2. In a combined har-row and roller,the combination of the main frame,the roller disposed centrally with lrelation thereto, the verticallymovable easter-Wheels at thefront and rear ends of said frame, the U-shapedv harrowframes, at the front and rear ends of said main frame and having the front ends of their arms pivoted to the sides thereof, and to the transverse portions of which U -shaped harroW-frames the upper portions of the harroW- teeth aredireotly attached, levers attached directly to said barrow-frames, means to lock said levers at any desired adjustment, and the longitudinallymovable seat supported on the main frame and adapted to be disposed Vin front or rearof the roller, substantially as described.

In testimony that l claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

LORENZO DOW BUTLER.
